Connecting The Inverter Manager; Connecting The Signal Source; Connecting The I/O Box To The Voltage Supply - SMA INVERTER MANAGER Instrucciones De Instalación

4 I/O Box
Position Designation
A Digital inputs for connecting a signal
source (inputs DI0 to DI5 can be
assigned; all other inputs have no
function)
B Maintain the default setting: X1 = 1,
X10 = 0
C Connection of the Inverter Manager
D Connection of the electricity supply
E Maintain the default setting: 1 = Dual,
2 = Initial
4.3.2 Connecting the
Inverter Manager
Do not connect during operation
Do not connect the I/O Box to the Inverter
Manager during operation. Errors might occur
that cannot be detected immediately.
• Disconnect the Inverter Manager from
voltage sources.
• Connect the I/O Box with the Inverter
Manager.
• Reconnect the Inverter Manager to the
voltage supply.

V) with Digital Output Signals
4.3.4 Connecting the I/O Box to
the Voltage Supply
Connect the 12 Vdc to 36 Vdc connection line with
the terminal for the voltage supply. Connect the
grounding of the connection line to the "V" terminal
and connect the grounding pin (GND) if grounding
is present.
